Like the bird life, but even more so, these animals are nowhere plentiful, and the species collected were obtained over a prolonged period, and through traversing a tremendous extent of country. Sixty-four different species and subspecies were collected altogether, representing examples of almost every animal that lives on the shores of the Sahara and in its interior, and these have proved of the greatest scientific value to the authorities of the British Museum in linking up the mammalogy across a vast tract of Africa. The mammals of my first expedition were collected for Lord Rothschild, who generously presented a set of all species obtained to the British Museum, and I was glad to add the results of the second expedition to our national museum to make the whole as complete as possible. The collections contained no fewer than fifteen new species and eleven new subspecies, which Messrs. Oldfield Thomas and M. A. C. Hinton, of the British Museum, have declared to be one of the most remarkable collections of novelties ever secured in the history of mammalogy. I feel that, to give some impressions of the animal life of the land, they should be dealt with under one or two aspects. The first place of interest is the southern shore of the Sahara, particularly at the time of rains—August-September, or thereabouts. [Illustration: BIG GAME FROM THE SHORES OF THE SAHARA FINE HEADS OF WHITE ORYX AND ADDAX] To any caravan out on the trail rains are a tremendous discomfort, and with camels, in wet weather the drawbacks are increased. Yet it often falls to the lot of the traveller to journey through the worst of weather, and on my second expedition it happened to be my wish to reach the neighbourhood of the bush edge at the season in question because of the movement of game. In accomplishing this my caravan experienced outdoor conditions at their worst. Everyone knows the intensity of tropical storms in their wild, spasmodic outbursts. When the weather broke the caravan was beset with periods of low-flung thunder and lightning, hurricane winds, and torrential rains that swooped across the land with alarming rapidity and malignant fierceness. Enforced camps had to be hurriedly pitched to protect valued specimens and perishable baggage, while the work of skinning, which was always my concern, was impossible, even under canvas, owing to the fierceness of wind and driving rain.
